摘　　要：市域(郊)铁路在国际上称为市郊铁路或通勤铁路,国内的市域铁路、市郊铁路和大部分市域快速轨道、一部分都市圈城际铁路都是市域(郊)铁路。都市圈和通勤是市域(郊)铁路的两个核心要素,决定了市域(郊)铁路与城际铁路、城市轨道交通在功能定位、空间尺度和空间形式上有明显区别。适应定位,市域(郊)铁路在旅行时间、技术速度、站间距、票价水平、运输组织模式、利用既有线条件等方面应有不同于其他类型铁路的技术经济特征。City railways,suburban railways and some intercity railways in the metropolitan belong to commuter railways.The metropolitan area and commuting are the two core elements related to the city/suburban railway,which determines that the city/suburban railway is significantly different from the intercity railway and urban rail transit in terms of functional positioning,spatial scale and spatial form.Adapted to the positioning.the city/suburban railway should have different technical and economic characteristics from other types of railways in terms of travel time,technical speed,station spacing,fare levels,transportation organization mode,and the use of existing railway conditions.
